CAN-SOLDERING iViACHlNE.

SPECIFICATION forming part of Letters Patent No. 335,011, dated January26, 1886.

Serial No. 182,984, (No model.)

To all whom it may concern:

Be it known that I, WILLIAM D. BRooKs, of Baltimore, in the State ofMaryland, haveinvented a new and usef'ul Improvement in Gan- SolderingMachines; and I do hereby declare that the following is a full, clear,and exact description of the same.

In the can making machines heretofore used-such,for example, as thatshown in my 1o United States PatentNo. 256,098, of April 4, l882-thecans are carried by planetary movement upon a revolving table, and thusare revolved in turn before a flame or flames whereby the solder ismelted.

rIlhe invention is illustrated in the accompanying drawings, in whichFigure l repre seuls the machine partly in central vertical section, andpartly in side elevation, all as hereinafter fully explained. Fig. 2 isan en- 2o larged detail view in perspective of the soldering-iron,partofthe heating appa1'atus,and solder-applying device. Fig. 3 is ahorizontal section of the same. Fig. 4 is a vertical section of the partof the can and device for holding it down. Fig. 5 is an enlarged view ofdetails of the machine.

In these drawings, A represents the table upon which the mechanisms aresupported. It is made concave upon its upper surfacein or- 3o der tocatch the oil dripping from the machinery, and to cause it to flowtoward the center, where it may be drained through an opening, l, into acup below. Upon this table in the center thereof is fixed a post, B. Therevolving table (l is provided with a hub or sleeve,

@,surroundingthe postwhich passes up through the table. The lower end ofthe sleeve is connected to the ratchet-wheel d, below which is a smoothbearing-surface, e, fixed to or formare ing apart of the ratchet-wheel.Against this bears a brake, f, to steady the motion of the machine. Thebrake is operated by levers and adjustable weights, as shown in Fig. 1.The ratchet-wheel :is operated by a lever, D,

4 5 carrying a spring-pawl, g, which is moved by an arm, l1., workedwithin the cam shaped opening of the lever,as in the aforesaid patent.This arm is on the hub of the master-wheel E, and operates the lever Dto move the table 5o one step, and each revolution of the masterwheelEis driven constantly through the gears 2 and 3, the latter being on themain drivingshaft, and the master-wheel gears into the pinions t' on thespindles of the can-seats, which are mounted in sleeves of bracketsfixed to the table C, all as in my said patent, except that the spindlesare in a vertical position. and the can-seats are simply fitted to holdthe can and need not have any flamechamber or exposed surface of the canwhen in 6o place. A second hub, c', is fixed to the table O and extendsupward,encircling the post,and

i carrying a table, F, on which is pivoted a series of levers, lneach inline with the canseat, carrying on its upper end a hollow pin, i, thelower pointed end of which is adapted to bear upon the center of' thecan-cap. These pins have a hole at their lower end, to ventilate theinterioigto provide for the escape of steam, and to prevent heating.They have iixed collars 5 and 6, to retain themin the sleeve ends of thelever lr, and the spring 7 to keep them down, the pins thus being heldto the Cap with a yielding pressure. The inner ends of the lever khave-anti friction rollers 8, 75 which travel in the campath of acircular head` L, fixed on the upper end of the shaft. The high part ofthis canrpath` is horizontal, and extends the larger part of the wayaround the head from and including the position of 8o the burner, so asto hold the caps down in place while they are subjected to the heat,and. for a sufficient length ot' time thereafter to allow the solder tocool before the pin is lifted. The low part of the cam-path is shown onthe right of Fig. l with the pin raised from the can. rlhis low part ismade to extend overenough space to give the attendant sufficient time toremove the soldered can and replace it with an unsoldered can. Upon oneside of the table is fixeda standard, M, having a tubular extension, m,set vertically on its upper end. Vithin this tubular extension slidesfreely a rod, n, the upper end of which is bent inward toward the centerof the table and carries a socket, o, held to the bent end of the rod bybolt and nut passing through a slot in the said end, whereby it may beadjusted toward or from the center of the can.

rThe solder-iron P (shown more clearly in too Figs. 2 and 3) is providedwith a shank, p, the upper end of which passes loosely through thesocket o, being adjustable to proper position vertically by its ownweight. The soldering-iron is in the form of a thick plate curved tocorrespond with the curve of the cap and to fit its groove. By the sideof this soldering-iron is iixed a solder-feeding tube, Q, preferablybellshaped on its upper end, and adapted to receive wire solder and topermit the end ot' the wire solder to project through below and rest linthe groove of the canin which the edge of the cap rests. To the side ofthe soldering-iron is fixeda concave disk of metal, R, against which theflame plays .delivered from the pipe r, for the purpose of keeping thesoldering iron hot. The solder is melted by the heat of thesoldering-iron, the tube Q being sufficiently near the iron for thatpurpose. The lower end of the rod n is connected to the slotted end ofthe lever S, pivoted upon the standard s on the table A. The innerend ofthis lever has asmall roller, t,which travels upon a cam-shaped ange,10, on the under side of the master-wheel E. The lower part of this cam-path y extends around the greater part of the circumference of thewheel E, and when the small wheelt is bearing upon the low part of thepath the soldering-iron is lowered into the cap-groove. When the highpart of the cam marked G is brought around to bear upon the wheel t, itlifts the solderingiron out ofthe groove and clear of the can.

The machine shown is designed to have twelve can-seats, and in thismachine the high part ofthe cam should occupy about one-eighth of thecircumference of the wheel E, and it is arranged so that its forward endwill strike the wheel t just before the arm h operates to turn the tableC one step, and the length of the high part is sufficient to holdthesoldering-iron up until another can has been brought by therevolution of the table C into position under the end of thesoldering-iron. Then the low part lifts the Wheel t and allows thesolder-iron to descend. The movement of the soldering-iron is less thanone-fourth of anA inch, and the iiame plays constantly into the cup onthis side, so that it isconstantly heated.

I have shown the solder-feeding tube as a more convenient way to applythe solder; but the mechanism may be used with any means for bringingthe solder to the groove.

It will be understood that the step-by-step movement of the table isarranged accurately, so as to bring the can directly in front of thesoldering-iron and to hold it there whlle the can is revolving to meltthe solder and properl y apply it.

I have shown the lever S as movedby the 6o master-wheel E; but `I do notconfine myself to the precise construction of a camshaped ange upon themaster-wheel E. Itis suflicient that the arm n should be raised by anymechanism connected with the driving mechanism of the machine at theproper time.

I claim as my inventionl. In combination with revolving can-seatscarried on a table having stepby-step movement, a soldering-ironsuitably supported, a 7o solder-tube for supplying solder to the cantop,a flame-tube for applying the ame to the said soldering-iron, and meansfor automatically raising and lowering the said iron from the cap-grooveof the can, substantially as described. v

2. In combination with the revolving canseatscarried upon a table havingstep-by-step movement, a rod, n, sliding in suitable standards, asoldering-iron, P, supported thereby, 8o a lever, S, and cam 10, uponthe under side of the master-wheel, adapted to operate said lever S,substantially as described. f

3. In combination with the revolving can\y seats, mechanism for holdingdown the caps at the solderstation,x the verticallyadjustablesoldering-iron, means for automatically raising and lowering 'said iron,a solder-feeding tube arranged in the described relation thereto, and aflame-tube adapted to heat said iron, suby stantially as described.

4. In combination, the revolving can-seats, Y mechanism for holding downthe caps, the soldering-iron carried on the vertically-movable rod, thepiper, for delivering the iiame, and the concave disk ,Basecureddirectly to the soldering-iron between it and the ame, substantially asdescribed. 5

In testimony whereof I have signed my name to this speciication in thepresence of two subro i scribing witnesses.
